[Abstract]:In this paper, a lithium ion battery and super capacitor composite power supply and its control system for electric vehicles are proposed. The system has the function of braking energy recovery and serves as the main power source of the compound power supply system. The Li-ion battery pack modules are used to provide the energy needed for the load for a long period of time. The supercapacitor bank module is designed to meet the energy requirement of high power pulse current discharge with short load. Pulse current discharge measurement. Try. Hybrid pulse power performance tests, dynamic stress tests and in-city driving cycle tests were performed to verify the effectiveness of the designed composite power system. The function and practicability of the system are further verified by using the motor as the load drive. In the test of using the motor to simulate the actual driving of the electric vehicle, the electric vehicle starts. Cycles and accelerations are performed step by step to record the discharge voltage and current response of the battery pack and the capacitor group; In addition, the results of braking energy recovery are satisfactory.
